What are valence electrons?
Valency Chart - The charge on the ions formed by an element is called the valency of that element. The number of bonds that an atom can form as part of a compound is expressed by the valency of the element.

The number of protons in an atom of an element is called atomic number. Sodium Number of protons = 11 Atomic Number=11 Carbon Number of protons = 6 Atomic Number = 6 It is represented by Z. Atomic Number of an element=Number of electrons in an atom
Mass number of an atom is due to protons and neutrons. The total number of protons and neutrons present in an atom is its mass number. Mass Number=No. of protons+No. of neutrons A=P+N Mass Number of sodium is 23 Mass Number of carbon is 12 Mass number= Atomic number+Number of Neutrons
The outermost electron shell of an atom is called valence shell. The electrons present in outermost shell of an atom are called as valence electrons. The valence electron of an atom take part in a chemical reaction because they have more energy than all the inner electrons. For Example: (1) Sodium (Z=11) The electronic configuration of sodium is K ...
An element’s valence is the number of hydrogen atoms which can combine with or replace (directly or indirectly) one of the element’s atoms. Oxygen, for instance, has six valence electrons but its valence is 2.

Apr 16, 2024 · What are Valence Electrons? The electrons present in the outermost shell of an atom are called valence electrons. And the shell that contains the valence electrons is called the valence shell . Example - 1. Helium has 2 Electrons. All these are in K Shell (as K Shell can hold max 2 electrons).
5 days ago · Valency is also known as molecular weight. Valency is a measure of the combining power of an atom. The valency of an element is determined by the number of electrons in its outermost shell. The valency of an element can be increased either by gaining or losing electrons.
